Sur Prep AP-1 is an adhesion promoter that can be used in the place of scuff sanding between coats of paint. It helps to re-activate the surface of the paint for subsequent coats to be applied. It can also be used for enhancing the adhesion of paint used for stenciling to topcoats. It is sprayed as a thin, wet film using standard paint application methods such as HVLP guns, air-assisted airless spray guns, and electrostatic spray equipment. It eliminates ergonomic injuries associated with mechanical abrasion. Other features include reactivates more uniformly than scuff sanding, eliminates sanding dust which can be environmental hazard, and reduces flow time. It improves durability of paint, adds minimal weight (<1 kg/1000 m2) to the painted surface, sharpens paint edges, and sprays easily for large area applications. It is available in aerosol form for small area applications. Sur-Prep AP-1 has been used on commercial aircraft since 2008. For more information visit www.zipchem.com or call (408) 782-2335.
